Danica McKellar, best known as the girl next door Winnie Cooper from the hit show "The Wonder Years" celebrated a milestone birthday on January 3rd: her 40th. Since the show ended back in 1993, McKellar has had steady acting gigs, and even has some writing and directing credits to her name.

McKellar's birthday has us "wondering" about some of the other cast members. Keep clicking to take a then-and-now look at the show's actors (there are even a handful of now-famous people who you probably didn't know were in the show.)
